Why crude prices must go up

It may be difficult to look beyond the current pricing environment for crude oil, but the depletion of low-cost reserves and the increasing inability to find major new discoveries ensures a future of expensive oil. 

While analyzing the short-term trajectory of oil prices is certainly important, it obscures the fact that over the long-term, oil exploration companies may struggle to bring new sources of supply online. The year 2014 may be the worst year in the last six decades in terms of new oil discoveries (based on preliminary data). 

Worse still, last year marked the fourth year in a row in which new oil discoveries declined, the longest streak of decline since 1950. The industry did not log a single "giant" oil field. In other words, oil companies are finding it more and more difficult to make new oil discoveries as the easy stuff runs out and the harder-to-reach oil becomes tougher to develop. 

The inability to make new discoveries is not due to a lack of effort. Total global investment in oil and gas exploration grew rapidly over the last 15 years. Capital expenditures increased by almost threefold to $700 billion between 2000 and 2013, while output only increased 17% (see IEA chart). 


Despite record levels of spending, the largest oil companies are struggling to replace their depleted reserves. BP reported a reserve replacement ratio – the volume of new reserves added to a company’s portfolio relative to the amount extracted that year – of 62 percent. Chevron reported 89 percent and Shell posted just a 26 percent reserve replacement figure. ExxonMobil and ConocoPhillips fared better, each posting more than 100 percent.

Still, unless the oil majors significantly step up spending they will not only be unable to make new discoveries, but their production levels will start to fall (some of them area already seeing this begin to happen). The IEApredicts that the oil industry will need to spend $850 billion annually by the 2030s to increase production. An estimated $680 billion each year – or 80 percent of the total spending – will be necessary just to keep today’s production levels flat.
